Open up your Device Manager where you'll see your DVD DX Hardware Device that no longer works correctly. Click it, and then click uninstall. Once uninstalled you can reboot, or click 'scan for new hardware'. Either way Windows will find your Device again and reinstall the driver and probably fix the registry entries.

If that does not work, reboot your computer holding down F8 and select 'Load Last Known Good Configuration' before booting into Windows again. It'll restore your settings back when it didn't detect any problems.
